This invention is directed to a method of using a therapeutic composition comprising a compound of an alpha-ketoalkanoic acid (pyruvate) and/or its derivatives for the treatment of cytokine-mediated inflammatory conditions. The compound is an alpha-ketoalkanoic acid, a physiologically acceptable salt of an alpha-ketoalkanoic acid, an ester of an alpha-ketoalkanoic acid, or an amide of an alpha-ketoalkanoic acid.

The invention belongs to a biological dosemeter of ionizing radiation, in particular to application of high mobility group box 1 (HMGB1) as a biological dosemeter of ionizing radiation. After isolated cells especial blood is radiated, the increase of HMGB1 content is proportional to received ionizing radiation dose to form certain dose-effect relation, and the ELISA (Enzyme-Linked Immuno Sorbent Assay) method and other simple, convenient and feasible methods can be adopted for rapid detection after 24 h of irradiation. Thus, the HMGB1 can be used as the biological dosemeter of ionizing radiation; moreover, the HMGB1 can be used for measuring the biological radiation dose of human bodies and animals exposed to ionizing radiation.

The invention provides a rice stress resistance-related OsHMGB3 gene which is separated and cloned from a rice DNA (deoxyribonucleic acid) fragment. The gene contains the conserved domain of the HMG (high-mobility group) gene family, and is an HMGB (high-mobility group box) type member of the gene family. The OsHMGB3 gene is expressed after being induced by polyethylene glycol (PEG), high salinity, low temperature, high temperature and abscisic acid (ABA), and the over-expressed OsHMGB3 can enhance the osmotic stress resistance of rice at the seedling stage, and is related to rice stress resistance. The rice gene can notably respond to stress, can be applied to plant breeding for stress resistance, and can enhance the stress resistance of plants.
